2. Description of the Related Art

In recent years, with the rise of portable electronic devices havingcamera functionalities, the demand for an optical image capturing systemis raised gradually. The image sensing device of ordinary photographingcamera is commonly selected from charge coupled device (CCD) orcomplementary metal-oxide semiconductor sensor (CMOS Sensor). Inaddition, as advanced semiconductor manufacturing technology enables theminimization of pixel size of the image sensing device, the developmentof the optical image capturing system directs towards the field of highpixels. Therefore, the requirement for high imaging quality is rapidlyraised.

The traditional optical image capturing system of a portable electronicdevice comes with different designs, including a four-lens or afive-lens design. However, the requirement for the higher pixels and therequirement for a large aperture of an end user, like functionalities ofmicro filming and night view, or the requirement of wide view angle ofthe portable electronic device have been raised. But the optical imagecapturing system with the large aperture design often produces moreaberration resulting in the deterioration of quality in peripheral imageformation and difficulties of manufacturing, and the optical imagecapturing system with wide view angle design increases distortion ratein image formation, thus the optical image capturing system in priorarts cannot meet the requirement of the higher order camera lens module.

Therefore, how to effectively increase quantity of incoming light andview angle of the optical lenses, not only further improves total pixelsand imaging quality for the image formation, but also considers theequity design of the miniaturized optical lenses, becomes a quiteimportant issue.

The vertical coordinate axis of the characteristic diagram of modulationtransfer function represents a contrast transfer rate (values are from 0to 1). The horizontal coordinate axis represents a spatial frequency(cycles/mm; lp/mm; line pairs per mm). Theoretically, an ideal imagecapturing system can 100% show the line contrast of a photographedobject. However, the values of the contrast transfer rate at thevertical coordinate axis are smaller than 1 in the actual imagecapturing system. The transfer rate of its comparison value is less thana vertical axis. In addition, comparing to the central region, it isgenerally more difficult to achieve a fine degree of recovery in theedge region of image capturing. The contrast transfer rates (MTF values)with spatial frequencies of 55 cycles/m at the optical axis, 0.3 fieldof view and 0.7 field of view of a visible spectrum on the image planeare respectively denoted by MTFE0, MTFE3 and MTFE7. The contrasttransfer rates (MTF values) with spatial frequencies of 110 cycles/m atthe optical axis, 0.3 field of view and 0.7 field of view on the imageplane are respectively denoted by MTFQ0, MTFQ3 and MTFQ7. The contrasttransfer rates (MTF values) with spatial frequencies of 220 cycles/m atthe optical axis, 0.3 field of view and 0.7 field of view on the imageplane are respectively denoted by MTFH0, MTFH3 and MTFH7. The contrasttransfer rates (MTF values) with spatial frequencies of 440 cycles/m atthe optical axis, 0.3 field of view and 0.7 field of view on the imageplane are respectively denoted by MTF0, MTF3 and MTF7. The three fieldsof view described above are representative to the center, the internalfield of view and the external field of view of the lens elements. Thus,they may be used to evaluate whether the performance of a specificoptical image capturing system is excellent. The design of the opticalimage capturing system of the present invention mainly corresponds to apixel size in which a sensing device below 1.12 micrometers is includes.Therefore, the quarter spatial frequencies, the half spatial frequencies(half frequencies) and the full spatial frequencies (full frequencies)of the characteristic diagram of modulation transfer functionrespectively are at least 110 cycles/mm, 220 cycles/mm and 440cycles/mm.

If an optical image capturing system needs to satisfy with the imagesaimed to infrared spectrum, such as the requirement for night visionwith lower light source, the used wavelength may be 850 nm or 800 nm. Asthe main function is to recognize shape of an object formed inmonochrome and shade, the high resolution is unnecessary, and thus, aspatial frequency, which is less than 110 cycles/mm, is used to evaluatethe functionality of the optical image capturing system, when theoptical image capturing system is applied to the infrared spectrum. Whenthe foregoing wavelength 850 nm is applied to focus on the image plane,the contrast transfer rates (MTF values) with a spatial frequency of 55cycles/mm at the optical axis, 0.3 field of view and 0.7 field of viewon the image plane are respectively denoted by MTFI0, MTFI3 and MTFI7.However, the infrared wavelength of 850 nm or 800 nm may be hugelydifferent to wavelength of the regular visible light wavelength, andthus, it is hard to design an optical image capturing system which hasto focus on the visible light and the infrared light (dual-mode)simultaneously while achieve a certain function respectively.

A thickness of a single lens element at height of ½ entrance pupildiameter (HEP) particularly affects the corrected aberration of commonarea of each field of view of light and the capability of correctingoptical path difference between each field of view of light in the scopeof ½ entrance pupil diameter (HEP). The capability of aberrationcorrection is enhanced if the thickness becomes greater, but thedifficulty for manufacturing is also increased at the same time.Therefore, it is necessary to control the thickness of a single lenselement at height of ½ entrance pupil diameter (HEP), in particular tocontrol the ratio relation (ETP/TP) of the thickness (ETP) of the lenselement at height of ½ entrance pupil diameter (HEP) to the thickness(TP) of the lens element to which the surface belongs on the opticalaxis. For example, the thickness of the first lens element at height of½ entrance pupil diameter (HEP) is denoted by ETP1. The thickness of thesecond lens element at height of ½ entrance pupil diameter (HEP) isdenoted by ETP2. The thicknesses of other lens elements are denoted inthe similar way. A sum of ETP1 to ETP6 described above is SETP. Theembodiments of the present invention may satisfy the following relation:0.3≤SETP/EIN<1.

In order to enhance the capability of aberration correction and reducethe difficulty for manufacturing at the same time, it is particularlynecessary to control the ratio relation (ETP/TP) of the thickness (ETP)of the lens element at height of ½ entrance pupil diameter (HEP) to thethickness (TP) of the lens element on the optical axis lens. Forexample, the thickness of the first lens element at height of ½ entrancepupil diameter (HEP) is denoted by ETP1. The thickness of the first lenselement on the optical axis is TP1. The ratio between both of them isETP1/TP1. The thickness of the second lens element at height of ½entrance pupil diameter (HEP) is denoted by ETP2. The thickness of thesecond lens element on the optical axis is TP2. The ratio between bothof them is ETP2/TP2. The ratio relations of the thicknesses of otherlens element in the optical image capturing system at height of ½entrance pupil diameter (HEP) to the thicknesses (TP) of the lenselements on the optical axis lens are denoted in the similar way. Theembodiments of the present invention may satisfy the following relation:0.2≤ETP/TP≤3.

A horizontal distance between two adjacent lens elements at height of ½entrance pupil diameter (HEP) is denoted by ED. The horizontal distance(ED) described above is in parallel with the optical axis of the opticalimage capturing system and particularly affects the corrected aberrationof common area of each field of view of light and the capability ofcorrecting optical path difference between each field of view of lightat the position of ½ entrance pupil diameter (HEP). The capability ofaberration correction may be enhanced if the horizontal distance becomesgreater, but the difficulty for manufacturing is also increased and thedegree of ‘miniaturization’ to the length of the optical image capturingsystem is restricted. Thus, it is essential to control the horizontaldistance (ED) between two specific adjacent lens elements at height of ½entrance pupil diameter (HEP).

In order to enhance the capability of aberration correction and reducethe difficulty for ‘miniaturization’ to the length of the optical imagecapturing system at the same time, it is particularly necessary tocontrol the ratio relation (ED/IN) of the horizontal distance (ED)between the two adjacent lens elements at height of ½ entrance pupildiameter (HEP) to the horizontal distance (IN) between the two adjacentlens elements on the optical axis. For example, the horizontal distancebetween the first lens element and the second lens element at height of½ entrance pupil diameter (HEP) is denoted by ED12. The horizontaldistance between the first lens element and the second lens element onthe optical axis is IN12. The ratio between both of them is ED12/IN12.The horizontal distance between the second lens element and the thirdlens element at height of ½ entrance pupil diameter (HEP) is denoted byED23. The horizontal distance between the second lens element and thethird lens element on the optical axis is IN23. The ratio between bothof them is ED23/IN23. The ratio relations of the horizontal distancesbetween other two adjacent lens elements in the optical image capturingsystem at height of ½ entrance pupil diameter (HEP) to the horizontaldistances between the two adjacent lens elements on the optical axis aredenoted in the similar way.

A horizontal distance in parallel with the optical axis from acoordinate point on the image-side surface of the sixth lens element atheight ½ HEP to the image plane is EBL. A horizontal distance inparallel with the optical axis from an axial point on the image-sidesurface of the sixth lens element to the image plane is BL. Theembodiments of the present invention enhance the capability ofaberration correction and reserve space for accommodating other opticalelements. The following relation may be satisfied: 0.2≤EBL/BL<1.1. Theoptical image capturing system may further include a light filtrationelement. The light filtration element is located between the sixth lenselement and the image plane. A distance in parallel with the opticalaxis from a coordinate point on the image-side surface of the sixth lenselement at height ½ HEP to the light filtration element is EIR. Adistance in parallel with the optical axis from an axial point on theimage-side surface of the sixth lens element to the light filtrationelement is PIR. The embodiments of the present invention may satisfy thefollowing relation: 0.1≤EIR/PIR≤1.1.

The height of optical system (HOS) may be reduced to achieve theminimization of the optical image capturing system when the absolutevalue of f1 is larger than f6 (|f1|>f6).

When |f2|+|f3|+|f4|+|f5| and |f1|+|f6| are satisfied with aboverelations, at least one of the second through fifth lens elements mayhave weak positive refractive power or weak negative refractive power.The weak refractive power indicates that an absolute value of the focallength of a specific lens element is greater than 10. When at least oneof the second through fifth lens elements has the weak positiverefractive power, the positive refractive power of the first lenselement can be shared, such that the unnecessary aberration will notappear too early. On the contrary, when at least one of the secondthrough fifth lens elements has the weak negative refractive power, theaberration of the optical image capturing system can be corrected andfine tuned.

The sixth lens element may have negative refractive power and a concaveimage-side surface. Hereby, the back focal length is reduced for keepingthe miniaturization, to miniaturize the lens element effectively. Inaddition, at least one of the object-side surface and the image-sidesurface of the sixth lens element may have at least one inflectionpoint, such that the angle of incident with incoming light from anoff-axis field of view can be suppressed effectively and the aberrationin the off-axis field of view can be corrected further.

If lens elements are made of glass, the heateffect can be controlled and the designed space arranged for therefractive power of the optical image capturing system can be increased.Besides, the object-side surface and the image-side surface of the firstthrough sixth lens elements may be aspheric, so as to obtain morecontrol variables. Comparing with the usage of traditional lens elementmade by glass, the number of lens elements used can be reduced and theaberration can be eliminated. Thus, the total height of the opticalimage capturing system can be reduced effectively.

In addition, in the optical image capturing system provided by thedisclosure, if the lens element has a convex surface, the surface of thelens element adjacent to the optical axis is convex in principle.

The driving module may be the voice coil motor(VCM) which is applied to move the lens to focus, or may be the opticalimage stabilization (OIS) which is applied to reduce the distortionfrequency owing to the vibration of the lens while shooting.

At least one of the first, second, third, fourth, fifth and sixth lenselements of the optical image capturing system of the disclosure mayfurther be designed as a light filtration element with a wavelength ofless than 500 nm according to the actual requirement. The lightfiltration element may be made by coating at least one surface of thespecific lens element characterized of the filter function, andalternatively, may be made by the lens element per se made of thematerial which is capable of filtering short wavelength.

The image plane of the optical image capturing system according to thepresent application may be a plane or a curved surface based on theactual requirement. When the image plane is a curved surface such as aspherical surface with a radius of curvature, the angle of incidencewhich is necessary for focusing light on the image plane can be reduced.Hence, it not only contributes to shortening the length of the opticalimage capturing system, but also to promote the relative illuminance.

The Fourth Embodiment (Embodiment 4)

Please refer to FIG. 4A, FIG. 4B, and FIG. 4C. FIG. 4A is a schematicview of the optical image capturing system according to the fourthembodiment of the present application, FIG. 4B is longitudinal sphericalaberration curves, astigmatic field curves, and an optical distortioncurve of the optical image capturing system in the order from left toright according to the fourth embodiment of the present application, andFIG. 4C is a characteristic diagram of modulation transfer of a visiblelight according to the fourth embodiment of the present application. Asshown in FIG. 4A, in order from an object side to an image side, theoptical image capturing system includes an aperture stop 400, a firstlens element 410, a second lens element 420, a third lens element 430, afourth lens element 440, a fifth lens element 450, a sixth lens element460, an IR-bandstop filter 480, an image plane 490, and an image sensingdevice 492.

The first lens element 410 has positive refractive power and it is madeof plastic material. The first lens element 410 has a convex object-sidesurface 412 and a concave image-side surface 414, and both of theobject-side surface 412 and the image-side surface 414 are aspheric andhave one inflection point.

The second lens element 420 has negative refractive power and it is madeof plastic material. The second lens element 420 has a convexobject-side surface 422 and a concave image-side surface 424, and bothof the object-side surface 422 and the image-side surface 424 areaspheric and have one inflection point.

The third lens element 430 has negative refractive power and it is madeof plastic material. The third lens element 430 has a concaveobject-side surface 432 and a concave image-side surface 434, and bothof the object-side surface 432 and the image-side surface 434 areaspheric. The object-side surface 432 has three inflection points andthe image-side surface 434 has two inflection points.

The fourth lens element 440 has positive refractive power and it is madeof plastic material. The fourth lens element 440 has a convexobject-side surface 442 and a concave image-side surface 444, and bothof the object-side surface 442 and the image-side surface 444 areaspheric and have two inflection points.

The fifth lens element 450 has positive refractive power and it is madeof plastic material. The fifth lens element 450 has a concaveobject-side surface 452 and a convex image-side surface 454, and both ofthe object-side surface 452 and the image-side surface 454 are asphericand have one inflection point.

The sixth lens element 460 has negative refractive power and it is madeof plastic material. The sixth lens element 460 has a convex object-sidesurface 462 and a concave image-side surface 464. The object-sidesurface 462 and the image-side surface 464 both have one inflectionpoint. Hereby, the back focal length is reduced to miniaturize the lenselement effectively. In addition, the angle of incident with incominglight from an off-axis view field can be suppressed effectively and theaberration in the off-axis view field can be corrected further.

The IR-bandstop filter 480 is made of glass material without affectingthe focal length of the optical image capturing system and it isdisposed between the sixth lens element 460 and the image plane 490.

Please refer to the following Table 7 and Table 8.

The detailed data of the optical image capturing system of the fourthembodiment is as shown in Table 7.
